18/27. I've got 13 
There's a few I vaguely remember, but can't get them right now. This is great fun 
Music of those old games is still haunting me almost daily for the past 30 years. Not sure if it's a good thing
19/27
Did have to trial/error/swap around some of the titles of our well-beloved software house.. (and made it myself a little bit easier/convenient by having a look at the company's page @ gen.msx to freshen my memory.. ;-)
Some notes/hints from me regarding how to correctly type #10 & #27 (not really spoilers, but you could decide to read over it):
10: write title without article;
27: just the 'short' title, and write as on gen.msx, but without punctuation mark(s).
Capitals don't matter.
Curious what game matches no. 6 (I like the sound).. Quite sure I know it though..
(@msaad: if your hint regarding #25 (page 2) were to be correct (it seems the hint you give there is meant for another game/#number) it reveals too much I reckon.. ;-))
Edit: I just noticed what Meits was pointing out earlier, made me able to correctly guess some more titles.. 
Lame! ;-)
(And omg, I just now realize they are all game over themes.. (what the f* does 'ovo' mean anyway..? ) Proper reading / paying attention is an art also... ;-))
Arghhh... recognised a few more, but only matched up 3...
Guess I should play MSX games more often!

Whoops. Sorry about that. I'd go back and edit it, except I don't see an edit option. Though anyone who copies every single game name from that page and try it clearly has too much free time
Wow, almost there Guillian!
Missing 2, 5, 6, 7, 9 and 11...
